`Sl?IEICIFIGA'IION forming part of Letters Patent No. 747,433,6 ated December 22, 1903.

Application filed March 4., 1903.

To @ZZ whom it may concern:

Beit known that I, JACOB J AcoBsoN, a citi-Y zen of Sweden, residing at Warren, in the county of Warren and State of-Pennsylvania, have invented new and useful Improvements in Vises, of which the following is a specification.

This invention. relates to certain new and useful improvements in that class of devices known as vises and designed for holding various kindsof work to be operated upon by a drill or other form of boring-tool or implement or tool of any appropriate character; and the invention consists of the parts and the Vconstructions 'and combinations of' parts, which I will hereinafter describe andl In the accompanying drawings, formingA part of this specification, and in which similar characters of reference indicate like parts, Figure 1 is a plan view of a vise embodying my invention. Fig. 2 is a side elevation ofthe same. Figs. 3 and 4 are plan views of vises of somewhat modified form from the one shown in Figs. l and 2, but illustrating the salient features of the present invention.V Fig. 5 is a sectional view showing a portion of the base, the screw, the clamp, and the guide-rod.

The device shown in Figs. l and 2 is ofthe form which is commonly known as a drillf press vise, and it comprisesa base or body portion A, of circular or any other desired or appropriate form, having its under surface,

which vrests upon the usual drill-press table,

(not shown,) finished smooth to form a close -flt, said base or body being provided with a essentially angular inhorizontal section, and

the other, i, having a threaded hole in which operates a screw h, the inner end of which is provided with a clamp-g, whose operatingface is likewise formed with a vertical groove angular in horizontal section, said grooved Serial No. 146,052. (No model.)

faces of the clamp and postd serving as jaws 'between which the work to be operated upon 'against the work and held solidly in place by means of the screw h, operating through the threaded opening in the post-'L'.

In connection with the screw and clamp g l prefer to use a guide-rod w, fixed in the clamp and slidably mounted in a hole formed through the post i, as shown in Fig. 5, whereby the clamp g is maintained in such position that the groove in its face will always be in the proper position 'relative .to the groove in the face of the opposite post.

In Figs. 3 and 4 I illustrate two forms of vises somewhat different in design from the one shown in Fig. l and 2, but wherein the operations to be performed are carried out substantially in the manner hereinbefore described.

The device shown in Fig. 3 i's what is known as the ,solid centering-vise and it includes an appropriate body portion A", finished smooth on the under surface to t thedrill- Vpress table and having aslot c for the bolt which secu res thevise to the table,as explain ed in connection with Figs. l and 2. This body A has a thickened portion d', which answers substantially for the post d of Fig. 1, and the inner face of this thickened portion has the 'vertically-extending angular groove e', corre- IOC the post ft' of Fig. 1 and has a threaded opening for the operating-screw h', which carries on its inner end opposite the angularlygrooved face of the thickened portion d of the body a clamp g', substantially corresponding to the clamp of Fig. l, the work being held substantially as before described.

In Fig. 4 I illustrate a plan view of what is termed a swivel centering-vise, which is similar in its salient features to the vise oi Fig. 3, in that it has a slotted body A3, which is tted to the drill-press table. It also has a bowed neck p', an operating-screw h", and a clamp g" operating in conjunction with an angularly-grooved vertical face of a thickened portion d of the base. In Fig. 4, however, the vise is made of two members 10 l2 to produce the necessary swiveling action which is desirable in this form of vise, and to further this object I construct one of the said members 10 with a hub-like projection q, and I form the other member l2 with a corresponding recess r for said hub, whereby the member which carries the bowed neck is capable of a rotary action relative to the other member.

In order that the two members just described may be appropriately fitted together and locked firmly in any desired position, I employ a cap-screw n or substantially equivalent element, and a graduated scale v may be marked or secured on the body of the vise in such manner that the angle of inclination of the member 10 may be conveniently and quickly read from this scale. With this type of device the angular grooves which hold the work may be brought into any desired angle with the vertical line which represents the axis of the drill, and dilling and centering may be accomplished at any desired angle.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. In a vise, the combination of a base portion adapted to be fitted to a table, said base having two integral walls extending vertically above the plane of its top surface, one of said walls having a vertical groove in its inner face and the other wall pierced with a threaded opening; a screw engaging said lastnamed opening, a clamp on the inner end of the screw andv having its greatest length parallel with the projection of said walls; and a guide-rod connected with the clamp and slidable through one of said vertical walls.

2. In a vise the combination of a base member havinga rigid vertical extension provided with a recess in its vertical face,a second member having an opening to receive the work, said last-named member having a groove in a wall of its opening and having a projection to turnably tit said recess, a bolt passing centrally through said projection and also through the vertical extension of the base member,ascrew disposed parallel with the bolt about which the said members turn one relative to the other, and a grooved face-clamp on the inner end of said screw.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

JACOB JACOB-SON.
